Observer-Based Output-Feedback Backstepping Stabilization of Continua of Hyperbolic PDEs and Application to Large-Scale Coupled Hyperbolic PDEs
Jukka-Pekka Humaloja, Nikolaos Bekiaris-Liberis
We develop a non-collocated, observer-based output-feedback law for a class of continua of linear hyperbolic PDE systems, which are viewed as the continuum version of , genera…

Florent Koudohode, Nikolaos Bekiaris-Liberis
We develop a switched nonlinear predictor-feedback control law to achieve global asymptotic stabilization for nonlinear systems with arbitrarily long input delay, under state quant…
Backstepping Control of Continua of Linear Hyperbolic PDEs and Application to Stabilization of Large-Scale Coupled Hyperbolic PDE Systems
Jukka-Pekka Humaloja, Nikolaos Bekiaris-Liberis
We develop a backstepping control design for a class of continuum systems of linear hyperbolic PDEs, described by a coupled system of an ensemble of rightward transporting PDEs and…

Nonlinear Bilateral Output-Feedback Control for a Class of Viscous Hamilton-Jacobi PDEs
Nikolaos Bekiaris-Liberis, Rafael Vazquez
We tackle the boundary control and estimation problems for a class of viscous Hamilton-Jacobi PDEs, considering bilateral actuation and sensing, i.e., at the two boundaries of a 1-…
Compensation of Actuator Dynamics Governed by Quasilinear Hyperbolic PDEs
Nikolaos Bekiaris-Liberis, Miroslav Krstic
We present a methodology for stabilization of general nonlinear systems with actuator dynamics governed by general, quasilinear, first-order hyperbolic PDEs. Since for such PDE-ODE…
